Abstract Background This study aimed to explore the preoperative risk factors related to blood transfusion after hip fracture operations and to establish a nomogram prediction model. The application of this model will likely reduce unnecessary transfusions and avoid wasting blood products. Methods This was a retrospective analysis of all patients undergoing hip fracture surgery from January 2013 to January 2020. Univariate and multivariate logistic regression analyses were used to evaluate the association between preoperative risk factors and blood transfusion after hip fracture operations. Finally, the risk factors obtained from the multivariate regression analysis were used to establish the nomogram model. The validation of the nomogram was assessed by the concordance index (C-index), the receiver operating characteristic (ROC) curve, decision curve analysis (DCA), and calibration curves. Results A total of 820 patients were included in the present study for evaluation. Multivariate logistic regression analysis demonstrated that low preoperative hemoglobin (Hb), general anesthesia (GA), non-use of tranexamic acid (TXA), and older age were independent risk factors for blood transfusion after hip fracture operation. The C-index of this model was 0.86 (95% CI, 0.83–0.89). Internal validation proved the nomogram model’s adequacy and accuracy, and the results showed that the predicted value agreed well with the actual values. Conclusions A nomogram model was developed based on independent risk factors for blood transfusion after hip fracture surgery. Preoperative intervention can effectively reduce the incidence of blood transfusion after hip fracture operations.

Primary Thas

Introduction: Although total hip arthroplasty (THA) is an effective treatment for end-stage arthritis, it is also associated with substantial blood loss that may require allogeneic blood transfusion. However, these transfusions may increase the risk of certain complications. The purpose of our study is to evaluate: (i) the incidence/trends of allogeneic blood transfusion; (ii) the associated risk factors and adverse events; and (iii) the discharge disposition, length of stay (LOS), and costs for these patients between 2009 and 2013. Methods: The National Inpatient Sample database was used to identify 1,542,366 primary THAs performed between 2009 and 2013. Patients were stratified based on demographics, economic data, hospital characteristics, comorbidities, and whether or not allogeneic transfusion was received. Logistic regression was performed to evaluate the risk factors for transfusion and postoperative complications. Results: From 2009 to 2013, allogeneic transfusions were used in 16.9% of primary THAs, with a declining annual incidence. Except for obesity, all comorbidities were associated with increased likelihood of receiving a transfusion. Allogeneic transfusion patients were more likely to experience surgical site infections or pulmonary complications (p<0.001 for all). These patients were more likely to be discharged to a short-term care facility (p<0.001). Additionally, they had a greater mean LOS (p<0.001) and higher median hospital costs and charges when compared to their non-transfused counterparts. Conclusions: While the observed decline in allogeneic transfusion usage is encouraging, further efforts should focus on preoperative patient optimisation. Given the projected increase in demand for primary THAs, orthopaedic surgeons must be familiar with safe and effective blood conservation protocols.

Emergency Cesarean

Background: Cesarean section delivery causes major risk factors in terms of intraoperative performance and blood loss while blood transfusion is a promising factor in emergency care in case of blood unavailability. Women undergoing cesarean section routinely require blood cross-matching. Aim: The present study aimed to evaluate the pattern of blood transfusion among women who underwent c/section at the tertiary care center. Materials and Methods: This cross-sectional study was conducted on 745 pregnant women who underwent cesarean section at Obstetrics & Gynaecology department of Quaid-e-Azam International Hospital Islamabad and PAF hospital Masroor, Karachi for duration of six months from January 2021 to June 2021. The demographic details, incidence of cesarean section, blood transfusion indications and types were recorded. Antenatal intraoperative and pre-operative details were also noted. Complications regarding blood transfusion were analyzed using multivariable analysis and EPI-statistical software v 3.5.3. Results: Of the total 745 cesarean sections, the prevalence of blood transfusion was 10.1%. About 75 women transfused 216 units of blood with packed cells tailed by Fresh Frozen Plasma (FFP). The prevalence of emergency cesarean section was 61 (81.3%) while general anesthesia was utilized in 27 (44.3%) cases. Fetal distress and placenta praevia were the common indications of cesarean section. Placenta praevia Respiratory rate (RR) was 5.01 (p<0.001). Other obstetric complications and risk factors were anemia, antepartum hemorrhage, hypertension, and previous cesarean section. The cross-matched transfusion ratio was 9.93 while the transfusion index and probabilities were 0.078 and 10.1 respectively. Conclusion: Our study found a higher prevalence of blood transfusion risks among pregnant women who underwent cesarean section. It has been observed that the risk of blood transfusion increased with placenta previa, preoperative maternal anemia, placenta abruption, and second stage cesarean section. During the antenatal period, the need for blood transfusion might be reduced with an increased concentration of maternal hemoglobin.
